MACHINE FOR SKIVING COUNTERS FOR BOOTS AND Specification of LettersPatent No. 28,531, dated May 29, 1860.

To all whom 'it may concerfv: A

Be it known that I, VILLIAM A. BACON, of Campello, in the county ofPlymouth and State of Massachusetts, have invented a new and usefulMachine for Skiving Counters for Boots and Shoes; and I do herebydeclare the same to be fully described and represented in the followingspecification and the accompanying drawings, of which- Figure l, is atop view; Fig. 2, a front elevation; Fig. 3, a side elevation, and Fig.4, a longitudinal section of it.

In such drawings, A, denotes the frame or table for supporting theoperative parts. This frame carries a driving shaft on which a feedwheel, C, is xed, the said shaft and wheel being arranged in the frameor table and relatively to the upper surface thereof as seen in Figs. 2,and 4.

Directly over the upper part of the periphery of the feed wheel, thereis a spring presser, D, which consists of a strong spring, a, and anadjustable bearer, b, the latter being xed to the spring by one or moreset screws, c, passing through a slot, d, and screwed into the spring atits front end, the other end of the spring being fastened to the frame,A. The presser rests and moves against a standard or bearer, E, servingthe two fold purpose of supporting the presser and the piece of leather,while the former is in movement and the latter is being cut or reduced.

The standard, E, projects upward from a block, I-I, which is placed onthe table and in rear of the feed wheel, and has adjusting screws markeda2, w, y, y, by which its elevation with respect to the table and thefeed wheel may be varied or adjusted and with a movement parallel to therear face of the feed wheel.

In connection with the feed wheel, the frame and the standard, E, arocker or lever knife, F, is employed, it being arranged and formed asshown in the drawings. It is or should be so applied to the block H, asto enable the angle of its cutting edge, f, with respect to theperiphery of the feed wheel, to be varied as circumstances may require.At the angular bend g, of the said knife a screw, z., passes downthrough the knife and is screwed into the block H, the head of the screwresting on the upper surface of vthe knife. Another screw, z', isscrewed through the rear part or arm of the knife and against the blockIFI and serves with the screw, 7L, at the fulcrum of the knife to enableangular adjustment of the knife edge to the top surface of the table toto be made or changed as may be required.

By revolving the feed wheel in the direction of the arrow, m, andinserting a counter or piece of leather between the feed wheel and theframe, and pressing it up to the bearer E, such piece of leather will beforced against the edge of the knife, and as the leather continues to beadvanced, the knife will cut or chamfer it along its edge, whether suchedge be straight or curved. The presser, in the meantime keeps theleather close down upon the feed wheel and gives way under the action ofirregularity in the thickness of the leather, the standard in themeantime serving to support the presser and keep it at its properdistance from the knife.

The arrangement of the parts is very favorable to cutting or chamferingcounters and enables them to be skived with great celerity andadvantage.

The adjustable block, H, applied to the table and with reference to thefeed wheel and made to support the knife and its separate adjustments asdescribed, is what gives value and importance to my counter skivingmachine as it enables me to adjust the knife vertically, relatively tothe periphery of the feed wheel in order to obtain just such a thicknessof the skived edge of the counter as may be desirable. The feed wheelnecessarily projects above the table in order to afford room for aworkman to apply a counter to the feed wheel and turn such counter toadvantage while the feed wheel may be in mot-ion.

I do not claim in combination with a feeding and gaging mechanism, aslotted arc and knife stock so that the knife or cutter may have therange of adjustment represented in and to adapt the machine to thevarious purposes described in the United States Patent No. 27,073, datedFebruary 7th, 1860 as my invention differs essentially therefrom, as itaords to the knife or cutter, a means of adjustment beyond that of achange in its inclination to the surface on which the leather may rest,and I employ no separate gage that is movable or adjustable toward andaway from the feed wheel.

I do not claim the mode of adjusting the edge or position of the knifeand its distance from the Sole rest as shown in the United States PatentNo. 21,760, as a apply the knife to, and make it adjustable on itscarrier or block and I make this block adjustable, parallel to the feedWheel. I could not to any practical advantage apply the block H, so asto be tipped for the purpose of varying the angular position of theknife relatively to the circumference of the feed Wheel, because tbetipping of such block 0W- ing to the elevation of the feed `Wheel aboveR.
